Ann EUGENE KLEIN, or g ruRNs'rILE MECHANISM Application filed January15, 1930. 'Serial No. 420,840.

The main object of this invention is to provide a turnstile as now usedin train sta-.

tions of transport systems which is simple in design and constructionand relatively in-.

expensive in cost. V J Another object of the inventlon is to. provide a'turnstile for transport systems in which the passenger deposits a comin the coin box remotely located from the device which energizes asolenoid releasing the turnstile mechanism to permit the passage of thepassengers. V V

Still another object of the invention is to provide a turnstile which iscoin released, or whose latching means are com released upon thedepositing of a coin and which may be rotated in one direction but willremain locked when rotated in the opposite direction until such time asa coin is deposited p in the mechanism.

The above and other objects will become apparent in the descriptionbelow in which characters of reference refer to like-named parts in thedrawing.

-Referring briefly to the drawing, Figure 1 is a top plan view of theturnstile mechanism showing a coin box applied thereto.

Figure 2 is a fragmentary section side elevational view of Figure 1showing the positioning plungers.

Figure 3 is a longitudinal sectional elevational View taken on line 3-3of Figure 1.

Figure 4: is a cross sectional view taken on line 4.4L of Figure 3.

Figure 5 is a fragmentary view similar to Figure 3 showing the lockingmechanism in closed position.

Referring in detail to the drawing, the numeral 10 indicates a pedestalupon which the turnstile mechanism is mounted. This pedestal issurmounted by a circular cam ridge 11 which is provided with a pluralityof arcuately spaced apart cam depressions 12. The turnstile comprises acircular casing 13 having a hub 14 therein which is rotatably securedupon a king-pin 15. The casing is rigidly secured to turnstile arms 15which are pivotally spaced apart an areuate distance of 90 degrees sothat a pas senger may with convenience Walk through the enclosurebetween two of these arms;

' For each depression 12 in the cam ring l1 a plunger isprovided. These'plungers comprise a cylinder 16 which housesa coil spring 17. The. coilspring is adapted to yieldahly extend a cartridge 18 upon which ahemi-spheroid b01tedhead'19is mounted; the head'being adapted to ride inand out of the depressions'12 upon the cam ring 11, saidiplungers beingadapted to rotate-with the turnstile arms 15. Y

l/Vithin thepedestal in'the compartment 20 thereof an electricallyoperated solenoid is provided with a reciprocating plungerj22 whichengages one end of a deformed locking lever 23. The locking lever 23 ispivoted intermediate its length upon a lug 24 and the upper or free endof said lever 25 projects at right-angles to the remainder of the leverand is formed into a hinged end which e n gages a hinged latching pawl26 The hinge is so formed that the latching pawl 26 may be freelyrotated and tripped when coming in contact with the heads 19 of theplunger as these plungers are rotated and moved with the turnstile armsin a clockwise'direction. A coil spring engages a rigid part of the camspring and issecured to the lever 23 intermediate its length andnormallyurges said lever to project said latchingpawl into en gaging positionwith the heads of said plungers. Airesilient finger '28 is secured tothe extension 25 of the swinginglever 23 and its free end engages thelatching pawl 26 urging this pawl constantly into extended position. Acoin box 29 may be located or mounted at a position-remote from theturnstile mechanism and is adapted through mechanical means to close acircuit through the cable-3O to energize the solenoid when-a coinhas'been deposited in member29 and. thus permit the entrance of thepassenger upon the station. The turnstile mechanism is adapted topermitthe passage of a single passenger into the enclosure when thepassenger stations himself between any pair of interseating arms 15 oftheturnstile. The coin is adapted to be deposited in the slot 31 of thecoin mechanism. Before this is. done, how- 33 ever, the turnstile islocked from being rotated in a counter-clockwise direction but may berotated freely and at will in a clockwise direction. This will permitthe passengers leaving the station to find ready exit past the turnstileif such passengers will walk between the arms in a clockwise direction.As previously stated, the coin is dropped into the coin box 29 andcloses a circuit through means not shown in the drawing and notpertinent to the application, and this circuit being closed energizes asolenoid 21. Previous to this time the latching pawl 26 rises in thepath of the passing plunger heads 19 and willnot permit the passage ofthese plungers, thereby locking the turnstile against rotation in acounter-clockwise direction. As soon as the coin is deposited and thesolenoid energized the lower end of the lever 23 is pulled toward thesolenoid thereby retracting the latching pawl 26 out of super-imposingposition over the cam ring 11 and thus permits the passage of members19. These members 19 are adapted to serve the double purpose ofpositioning the turnstile so that the arms of the turnstile will alwayscome torest in the same position and also these members 19 support ingthe movable parts of the turnstile between the cam track will tendtoward a noiseless performance of the device.

It is to be noted that certain changes in form and construction may bemade without departing from the spirit and scope of the invention.

We claim:

1. In a device of the class described, a pedestal, a rotatable turnstilemember, plungers projected from said rotatable member, a cam ringmounted on said pedestal, co-operating with said plungers and means onsaid cam ring for limiting the movement of said rotatable turnstile todegrees and means for locking said plunger against rotation in onedirections, depressions in said cam ring of the same number as saidplungers tolimit the movement of said rotatable turnstile member, amember adapted to project over said cam ring for locking said rotatablemember against rotation in one direction and electrically operated meansfor restricting said member.

2. In a device of the class described, a pedestal, a rotatable turnstilemember, plungers projected from said rotatable member, a cam ringmounted on said pedestal co-operating with said plungers, a leverpivoted on said pedestal an electrically operated solenoid for rotatingsaid lever and means on said lever normally projecting across the pathof said plunger to lock said plungers against rotation in one direction.

3. In a device of the class described, a pedestal, a rotatable trunstilemember, plungers projected from said rotatable member, a cam ringmounted on said pedestal co-operating with said plungers, a leverpivoted on said pedestal, an electrically operated solenoid for rotatingsaid lever, a latching pawl secured to said lever, said latching pawlbeing normally projected across the path of said plungers locking saidplungers against rotation in one direction.

4. In a device of the class described, a pedestal, a rotatable turnstilemember, plungers projected from said rotatable member, a cam ringmounted on said pedestal co-operating with said plungers, a leverpivoted on said pedestal, an electrically operated solenoid for rotatingsaid lever, a latching pawl secured to said lever, said latching pawlbeing normally projected across the path of said plungers locking saidplungers against rotation in one direction, said latching pawl beinghingedly connected to said lever, said latching pawl permitting the freepassage of said plungers when rotated in one direction, and means forretaining saidlatching pawl in extended position on said lever.

In testimony whereof we atfix our signatures.
